Pneumatic aluminum alloy ball valve definition and working principle are introduced

pneumatic aluminum alloy ball valve in industry application is broad, the following by Ann to petrochemical introduces knowledge of pneumatic valve, pneumatic aluminum alloy under and working principle.

pneumatic aluminum alloy ball valve is evolved by the cock pneumatic valve. It has the same rotation movement, different is the cock body is ball, a circular hole or channel through its axis. Spherical and opening ratio should be such, that is when the ball rotation, should all present in the inlet and outlet sphere, thus blocking flow. This kind of pneumatic valve can be installed in any position in the pipeline.

pneumatic ball valve of pneumatic ball valve with pneumatic actuator. Pneumatic actuators execution speed is relatively fast, the fastest switching speed. Seconds/times, so usually also called pneumatic quick cut pneumatic ball valve. Pneumatic ball valve usually configure various accessories, such as electromagnetic air valve, air source treatment sanlian pieces, limit switch, locator, control box, etc. , in order to realize the local control and remote centralized control, in the control room can control the switch of pneumatic valve.

pneumatic aluminum alloy ball valve working principle is as follows:

. When the pneumatic actuators after connected with gas source circuit and system, and the air through A pipe tube into A cylinder (A or B B cylinder pushing the piston movement to end, so as to drive the rotation axis of rotation and the ball core °

. Pneumatic actuators at the top of the moving and visual, when green signs pointing to 'open' word mark pneumatic valve opens.
　　
　　. When the reply is light green light pneumatic valve is in open position, pneumatic valve in the closed position when the red light

. Adjustable pneumatic valve positioner pipe flow. Pneumatic valve seat adopts the elastic sealing structure, reliable sealing, easy opening and closing.
　　
　　. Pneumatic valve stem has inverted sealing bottoms type structure, pneumatic valve cavity when the abnormal pressure, pneumatic valve rod will not be impact.
　　
　　. Pneumatic piston type actuators with low friction materials bearing sleeve, inside and outside the cylinder body hard anodic oxidation of corrosion on the surface, greatly improving the service life of the cylinder.

pneumatic aluminum alloy ball valve is widely used in natural gas, oil, chemical industry, metallurgy, papermaking, electric power, mining, printing, dyeing, biological pharmacy, daily chemical, food and beverage, water treatment and air treatment and other industries fluid control or adjust the control, pneumatic instrument and automation systems.
